MCHINE FOR MAKIYNG SHEET'OR PLATE GLASS.

Patented May 28, 1907.

To all whom it may concern:

Be it known that I, WILLIAM W.' W. KEYES, of Alexandria, county of Madison, and State of Indiana, have invented acertain 5 new and useful Machine for Making Sheet or Plate Glass; and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein had to the ac-, companying drawings, in W 'ch like letters refer to like parts.

The object of this invention is to provide a machine for forming sheets of glass by rolling and drawing in contradistinction to blow- To accomplish this general object, the machine contains a tank for the lass in its molten state with a horizontal out et through which the glass may flow by gravit alone down over an inclined table to rolls w `ch receive the glass and form it by subse uent rolling and drawingof the same.' ong with the fore oing, means for regulating the flow of the g ass from the tank is provided and also a leer connected with the tank, and into which the glass iiows over they inclined table, andmeans is provided in connection with the foregoing to keep the glass'heated from the time it leaves the tank until it leaves the leer. j',

One feature vof the invention consistsin a plurality of rolls arranged-in independent series, each succeeding series rotating vat -a higher speed than the preceding series whereby the mass of glass is caused to travel at successively increasing speeds, so that the sheet of glass While bein rolled is pulled or drawn to stretch or straig ten it and prevent`wrin- A igiother feature of the inventionconsists in the glass cutting mechanism herein shown in connection with the foregoing for cutting the sheet .of glass into individual sheets.

For a comprehensive understanding of the invention, reference ishad to nying drawings in which4 Figure 1 'isa longitudinal vertical section of the machine, parts being broken away.

the accompa- .v Fig. 2 is a horizontal'section on the line 2-2 of Fig. 1. Fig. 3 is a side elevation of a part of the machine, parts being broken away or removed. Fig. 4 'is a cross-section on the line 4'-4 of Fig. 1, parts bein brokenaway. Y Fig. 5 is a cross section' on the line 5-,5 of

Fig. 1. Fig. 6 is an end elevation ofthe cut-` ting and delivering mechanism, their parts being shown in vertical cross-section and .partly broken away. Fig. 7 is an elevation of the cutting mechanism, parts being cross-section, and the changed osition of some ofthe parts .beingin dotted ines; Fig. 8 is la plan view of what is shown in Fig. 7. Fig. 9 1s a side elevation of the carriage containing the cutter and the supporting bar on v which it moves, the latter being broken away and the sheet of' glass being shown in section. Fi 10. is avertical section of Fig. -9 to the rig t of the center of saidiigure. Fi 11 is a cross-section of a'part of a sheet of g ass and of the supporting bar for the cutter carriage, the means for actuating the clam s appearing in elevation. Fig. 12 is a simi ar view at the point of connection of one of the clam s with the supporti-n bar but on a larger sca e than in Fig. 11.A Fig. 13 is a plan view of what is shown in Fig. 12 the clam ing means being in section and -parts vbro en awa Fig. 14 shows a part of Fig. 1 with drawing or starting plate in use.

Referring to the details of construction, 20 represents aglass tank for holdin the glass in the molten state with a-depen ing shield or damper 120.- 'A horizontal outlet along the glass -one end of saidtank is provided between the lower wall 121 and upper wall 122. The upper wall is. cut away at 123 to make room for the location and operation of a number- 4so as to regulate the opening between them and the wall 121 throu h which the.` lass may flow from the tank y avity. P ates 124 of some suitable materialclr are securedl on the blocks 21, that extend inward beyond the top of said 'blocks to engage the outer surface of the walll 122 so as to make a-tight closure between the blocks 21 and th wall 122 during the adjustment of the former as well as at all other times.

The movement of the blocks 21'to adjust the outlet opening from the tank is effected by levers 22, one pivoted to each block 21 and centrally pivoted to the lower end 'of bars 125 depending from across beam` 126 above. To the outer ends of the levers 22 rods24 are pivoted that extend up through IOO brackets 127 secured to the cross-beam 126, and the rods 24 are held in position `by nuts 128, so that by screwing or unscrewlng the nuts 128 the .size of the outlet opening beand in vthat leer the sheet of 'glass is both formed and annealed. To accomplish this it is necessary, 'of course, that the leer be heated, but with this peculiarA combination of the leerbeing adjacent to the tank of glass the heat from the glass flowing into the eer is suflicient for this urpose. And for the purpose of annealing t e glass 'it is necessary to reduce vthe 'temperature somewhat toward the outlet end, and, therefore,.the flues 29 are provided. Since the blocks 21 are vertically movable it is necessary to provide a movable topV to the end of the leer adjacent the glass tank to prevent the -escape of the heat. v Therefore, a movable top 26 is provided, secured along one edge of the locks 21, and at the other end sllps loosely onfthe top of the leer and in a recess under an overla ping socket piece 27.

An inc ined table 25, mad-e preferably of, asbestos, leads from the outlet openin of the tank downward to the rolls inthe ier It rests upon a transverse wallA 131.l As the molten glass flows by gravity down over the table 25, it encounters a primary set of forming rolls 30, said rolls being mounted upon suitable shafts 31 which project outside the leer. The lower rolls of said set are designed to support the mass of glass', while the u yper roll co-operates w'ith'o'ne of the lower rol s to lis.

convey and reduce' the thickness of the mass of glass as thelatter passes between them.

The rolls are preferably c overed withfasbestos, as shown atI 32, to withstand the heatl ofv the molten gl ass, and the rolls are lpreferably hollow. i

The second lower roll 30 is like the first lower roll 30 and revolves in the same direction and at the same speed. There is a secv shaft 33 outside the lower set of rolls.

ond set of three rolls 38 similar tothe first set, and another set of two .rolls 42 similar to the others. All the rol-ls are driven fromfa lower rolls are driven directly from said shaft through la pair of bevel ears. The

lowerl rolls 30 have on their sha ts 31 bevelv gears -34 that mesh with gears 134 on the shaft 33 which are of the saine size. The

gears 41 on them of the same'size that mesh withthe gears- 134 on the shaft. The gears.

'41are smaller than the gears 34. The shaft 43 of the lower roll 42 4has a `gear 44 `,that

meshes'with the ear v144.

The upper rol s 30, 38, and 42 lare driven by the ollowing means. ,The shaft 43. on the lower roll 42 has on one end a gear 37,

The

shown in dotted lines in Fig. 3, and meshes with a gear 35 on the shaft of the upper roll 42. An intermediate gear 36 transmits vthe power from the gear 35 to the gear 135 on vthe shaftofthe upper roll 38. An intermediate gear 36 transmits power from the last men tioned gear to the gear 23,5.gsecured on the shaft o the first upper roligBO. They ears 35, 135 and 235'a1e4 increased i gradually increased speeds'in the order of their distance from-the glass tank, and also the dimensions of these gears is such that all the rolls 3() will be driven at the same speed,

and all the rolls 38 at the same speed,'and all the rolls 42 at the same speed. The upper rolls are rendered vertically 'adjustable by the rods 136 and nuts 137,' as seen in Fig. 5,

adual y inldiameter so said upper rolls will travel at whereby the bearings 138 in which the tops o'f said rolls are mounted vertically movable and heldin position. Another sort and series of rolls 140 are provided on the shafts 240, which are driven by gears 244'and' 344. The rolls 140 are narrow, three or four being -oneach shaft, ,and the rolls on the different shafts are placed to alternate and interlace with each other, as appears in Figs. 1 Aand 2. This is to support the sheet of glass while it is hot.v Another set of rolls 142- are provided on shafts 143, and driven at the same speed rolls ,140 and' v142 are driven slightly faster than the preceding rolls.- The rolls 142 are farther apartthan the rolls 140, for when the sheet of glass reaches them it is coolerand stier. The shaft 33 is driven by a pulley 'as the rolls 140 and by the same means. The

At the outlet end of the leer there is an `,outlet opening 45 through which the glass 46 outside the leer similar to passesto a rol the rolls 142 and' driven in the same way and at the'same speed. :From that roll the sheetv of glass goes'to-the truck 70.- This truck carries a series of smaller rolls 7 1 which receive theA glass. Thel truck has'a pair of wheels that travel on another .truck 7 2.w hich runs in a transversey direction, as seen in Fig. 1. The rails 7 3 that carry the upper truck may be moved into alinement with the rails 74 forming a track on which the truck and sheet ofglass 100 may be removed. The first one of the rolls 471 is mounted'eccentrically and may be rotated bythe crank 75. The urpose of this is to lower the top surfaceo the roller so that it will run under the approaching' edge' of the glass sheet as thevtruck is moved in toward tr i leer. l When the truck is in place, the eccentric of the mounted roll l is turned so as to raise its upper surface.

It 1s, of course, necessary to sever the sheet as the same leaves the delivery opening 45, and to the accomplishment of this end, the j construction illustrated in Figs. 1, 2*, and 7 to 13 is employed. As before stated' the invention vrequires a construction of cutting mechanism that will positively insure -an accurate cut and while the sheet of lassis moving, and recourse is,` therefore, ad to the construction which will now be described.

By referring es ecially to Figs. 7 and 8, the numeral 48 esignates a bar orltrack arranged in proximity to the delivery end of thA loer 28 and extending in a direction par-- allel with. the plane or path of movement of the sheet as the same is deliveredl from said leer. This track is preferabl formed of angle-iron, and mounted on sai track is a traveling carria e 49 to which are journaled the rollers 50 w 'ch travel on the flanges of the track 48 to enable the carriage 49 to readily work thereon. A transverse su porting bar 51, also of angle iron, is provide with a bifurcated bracket 52, the legs of which are suitably pivoted, as at 53 to the carriage 49, and consequently said supporting bar may be readily swung upon its pivots in a vertical plane. A cutter carriage 54 is mounted upon the bar 51,- said carriage being provided with rollers 55 which move upon the bar 51, and one face of saidcarriageisA provided with outwardly extending arallel perforated lugs 56 in-which is seate a vertically.arranged cutter holder 57, the lower end of which is divided and embraces a diamond or'cutter 58 designed to act upon the surface of the lass. A set screw 59 is carried by the divided end of the holder 57 through the medium of which theA cutter 58 is held in said holder, and the latter is also surrounded by a coil spring 60 the up er end of which takes against the upper en of the` lug 56, said spring normally exerting its tension to force the cutter into -yieldin contact with the surface of .the glass. ournaled upon the free end of the supporting bar 51 is a s ool or drum 61, the latter being provided wit a crank 62 for rotating thespool or drum, and coiled upon said spool or drum is a `cable 63 which is connected with the carriage 54. Consequently when the `cable 63 is wound upon said spool or drum 61, the carriage 54 is caused to travel u on the support-j ing bar 51 and across the s ace of the glass, thus causing the cutter 58 to act -upon the glass and to sever the same in a plane transverse to the direction of its movement. It is also held desirable that when the sheet of glass is delivered beneath the supporting bar 51 to be acted upon by the cutter, said sheet should have a substantially fixed relation to said sup orting bar, and in order to attain this desira le end, a pair of reversely arranged curved clamps 64 is employed, said clamps being arranged at the under side of the bar 51, and provided with'upwardly extendin bolts 65 u on which are threaded iange nuts 66. he bolts 65, however, pass through elongated slots, thereby form# ing guides and permitting the clam s 64 to have a limited movement toward) and .45 for engagement with a new away from theedges of the glass sheet. To

effect the movement of the clamps referred to a lever. 67'is pivoted at one` s ide ofthe barA 51, as'at 68,.and connected with said leverI above and belowV the fulcrum 68 are links .69

Awhich are also pivotally connected with the clamps 64. It will thus ,be evident that the lever 67, the clamp 64 will be caused Vto either engage the edges of the glass sheet or be released therefrom. The bar 51 is also provided with a downwardly extending lugI 0 against which the sheet of vglass is. de-

signed to rest, andby reason of said lug, said sheetwill be firmly held, when the clamps are in engagement with the edges thereof.

Thus it win be geen than binding mation will exist betweenlth'e bar 51 and the glassv sheet, and as the latter'is advanced'under the movement imparted by the rolls within.

the chamber 58', the lbar 51 will be moved with the sheet, andthe carriage 49- caused to travel forwardly on the track 48. During this movement of the bar 51 with the sheet,

the carriage 54 is 'drawn across the surface ofthe gllass sheet, and the cutter thereby severs t at portion of the sheet in advance of the bar 51. The severed ortion is deposited upon the truck 70, and) clamp .64 will be free from engagement with the severed ortionv of the sheet, and by swinging the Ear 51 u on the pivots 53 in an upward direction, the Iar 51 may be returned to a point in proximity to the delivery throat sheet to effect a new'cut.

An arm is secured tothe truck frame, as seen Ain Fig. 6, that extends up into the ath of the supporting bar of the cutter mec anism for serving as a stop orlimit of. move'- ment to the cutter mechanism when the latter i'sbeing moved to its starting position so that each sheet of' lass cut oi will be of the same size. Also w en the truck is moved after the glass is severed, this. arm 95 will move the cutter mechanism with it until the cutter mechanism is elevated out of the way .of the arm. This mechanically takes the cutter mechanism away' from the longitudinally moving end of the uncut; she'et 100 of the glass. When ready tocut another sheet,

the cutter bar is elevated and moved back in place andl against the arm.95 on thesubse-v "glass may flowfrom the tank to the sheet- I orming mechanism. l j

though at first it extends beyond the. first set of ro ls slightly toward the tank, so that the glass in lo'wing down the chute Will come in contact with it.` Then the rolls are started,

and they roll the starting plate 90 throughA the leer, and it draws the sheet of glass after it. Whenthe starting plate has passed thus through` the leer, it is removed, and then the sheet of glass thereafter continuously draws the molten glass through the rolls.
